According to the invention, a marine panel hanging assembly is providedfor hanging noncombustible insulative wall panels in a spacedrelationship with a metal lic hull or bulkhead on a ship. The spacerequirement is for fireproofing and hence a minimum heat transferbecomes extremely desirable which is the general purpose of the instantinvention. In one embodiment for hanging panels in spaced relationshipwith the metallic hull, the in-place hull stiffener is utilized forattaching the panel hanging assembly. Here a pair of insulative blocksis placed on each side of the hull stiffener member and clamped aroundthe hull stiffener member by a clamp screw passing through metallicclamp plates on each side of the insulative blocks. The clamp plates arespaced from the metallic hull stiffener and the front clamp plate hastapped screw holes for attaching wall panels thereto via panel screws.This arrangement results in no metal to metal heat transfer between themounting screws of clamp plate to which the wall panels are attached andthe metallic hull, thereby maximizing heat insulation.

A second embodiment for attachment to bulkheads accessible from eachside lines in placing an insulative block on each side of the bulkheadwith a tubular insulator passing through the bulkhead and partiallythrough at least one of the insulative blocks with a clamp. A clampplate is then placed on the outer exposed faces of the insulative blockswith a clamp screw passed through the clamp plates and the tubularinsula tor for clamping the entire assembly to the bulkhead. The panelscan then be hung on the clamp plates via threadable engagement with apanel screw and the clamp plates themselves, again resulting in no metalto metal path for heat transfer between the panels and bulkhead.

A third embodiment is utilized in hanging panels on a bulkhead havingonly one accessible side. In this embodiment. an insulative block isplaced against the bulkhead with a metallic saddle attached via saddlebolts passing through the saddle and engaging a tapped hole in thebulkhead. The saddle has a channel for receiving a second insulativeblock after which a bolt plate insulator carrying a nut plate is placedwithin the channel, the nut plate and bolt plate carrying panel screwholes for threadably engaging a panel with the nut plate.

DETAILED DESCRIPTION OF THE DRAWING Referring to FIG. 1, a section of ametallic hull is shown at 11 having a metallic hull stiffener l2 weldedthereto at 13. Stiffener 12 has a face section 14 to which is attachedwall panels 16 and 17 via panel screws 18 and 19.

Referring to FIG. 2, a typical prior art panel hanging technique isshown having a hull 11 with a hull stiffener 12 welded thereto at 13. Ahanging bracket 21 is welded to the face section 14 of stiffener 12 at22. Panels 16 and 17 are attached to hanging bracket 21 via threadedscrews 18 and 19.

Referring to FIG. 3, another prior art technique is .shown where a steelhull shown at 11 has hull stiffener 12 welded thereto at 13. Insulativeblock 23 is held against face portion 14 of stiffener 12 via panelscrews 18 and 19 passing through panel sections 16 and 17 and insulativeblock 23 and held in threadable engagement with face portion 14.

Referring to FIGS. 4 and 5, steel hull 11 has hull stiffener 12 weldedthereto at 13 with face portion 14 sandwiched between insulative blocks26, 27, 28 and 29. Insulative blocks 26, 27, 28 and 29 are held inabutting relationship with face portion 14 of hull stiffener 12 viaclamp plates 31 and 32. Clamp plates 31 and 32 are held in a clampingrelationship with the insulative blocks 26, 27, 28 and 29 and faceportion 14 of reinforcer 12 via clamp screw 33 and clamp nut 34. Clampplate 31 has a pair of panel screw holes 36 and 37 in abuttingrelationship with panel screw holes 38 and 39, respectively, of wallpanels 16 and 17.

Referring to FIG. A, panels 16A and 17A are shown coupled to clamp plate31A via clamp plate screw 40 being in threadable engagement withthreaded aperture 35 of clamp plate 31A. Clamp washer 40A is carriedwithin mating circular recesses in panels 16A and 17A.

Referring to FIG. 6, a curved metallic hull portion 11A is shown with ametallic reinforcer 12 welded thereto at 13. Metallic reinforcer 12 hasa face portion 14 in parallel relationship with the centerline (notshown) of the hull. Here, bevelled insulative blocks 41, 42 and 43 areclamped around face portion 14 of metallic hull reinforcer 12 in thesame manner via clamp plates 31 and 32, clamp plate screw 33, and clampplate nut 34. Wall panels 16 and 17 are held via panel screws 44 and 46in threadable engagement with clamp plate 31. Panels 16 and 17 are heldvia the bevelling of insulative blocks 41 and 42 and 43 in a generalparallel relationship with metallic hull section 11A.

Referring to FIG. 7, a bulkhead section 51 is shown having an aperture(not shown) therein which receives tubular clamp screw insulator 52.Tubular clamp screw insulator 52 is recessed within insulative blocks 53and 54 which are held against bulkhead 51 via a clamp screw 56 on theface of a front clamp plate and panel nut plate 57 via a clamp screw 58passing through front clamp plate 57, insulative block 54, tubular clampscrew insulator 52, insulative block 53 and back clamp plate 58. Frontclamp plate 57 has panel screw holes (not shown) substantially identicalwith panel screw holes 59 and 61 and front clamp plate 57.

Referring to FIG. 8, a bulkhead 62 is shown having a insulator block 63in abutting relationship therewith. A saddle plate 64 has a pair ofsaddle tabs 66 and 67 with saddle bolts 68 and 69 therein passingthrough insulative block 63 and in threadable engagement with bulkhead62. Saddle bracket 64 has an upper saddle skirt 71 and a lower saddleskirt 72 dimensioned for receiving insulative block 73. Upper saddleskirt 71 and lower saddle skirt 72 are also dimensioned for slidablyreceiving insulative block 74 and nut plate 76 carried within a recess77 in the back surface of insulative block 74. Insulative block 74 haspanel screw holes 78 and 79 therein and a raised face area for directcontact with panels.

Referring to FIG. 9, insulative block 63 is clamped to a bulkhead (notshown) via bolts 68A and 69A in saddle 64A. The upper saddle skirt 71Ahas an insulator holding screw hole 75A and a lower saddle skirt 72A hasan insulator holding screw hole 75B.

Referring to FIGS. and 11, a modification of the embodiment in FIGS. 4and 5 is illustrated. Here the hull stiffener 12A is T-shaped instead ofL-shaped. The marine panel hanging assembly itself is symmetrical withinsulative blocks 26A, 27A and 28A, symmetrically disposed around face14A of hull stiffener 12A and between front clamp plate and nut plate31A and back clamp plates 32A. I-Iere two clamp screws 33 and nuts 34are utilized.

Referring to FIG. 12, a modification of the embodiment of FIGS. 10 and11 is shown utilizing a J-shaped front clamp plate 31B necessitating avariation of insulative blocks 28B, 29A and 29B.

OPERATION Referring back to FIG. 1, it can be seen that wall panels 16and 17 are spatially disposed from metallic hull section 11 which isrequired for fireproofing. In this typical embodiment, the wall panels16 and 17 are attached by panel screws 18 and 19 and the generalappearance will be the same whether the prior art is utilized or theinstant invention.

FIG. 2 illustrates a typical prior art method of hanging the panelswhere a panel hanging bracket 21 is welded at 22 to face portion 14 ofan in-place hull stiffener 12 which is welded at 13 to hull 11. Thedisadvantage here, of course, is that there is a direct metal to metaltransfer between hull 11 and the backs of panels 16 and 17.

Referring to FIG. 3, bracket 21 has been replaced with an insulativeblock 23 with hanging screws 18 and 19 in threadable engagement withapertures in face portion 14 in stiffener 12. The main disadvantage herelies in the direct heat transfer from panels 16 and 17 to hull 11through stiffener 12 and panel screws 18 and 19.

Referring to FIGS. 4 and 5, one embodiment of the present invention isutilized whereby the face portion 14 of hull stiffener 12 is sandwichedin between a plurality of blocks 26, 27, 28 and 29 and held in place byclamp screws 33 and clamp nut 34 passing through clamp 31 and 32. Clampplate 31 is bent around one side of the assembly. Clamp plate 31actually forms a panel nut plate and is threadably engaged with panelscrews passing through panel screw holes 38 and 39 in panels 16 and 17and is in threadable engagement with holes 36 and 37 in front clampplate 31. Here it can be seen that there is no metal to metal heattransfer between hull and wall panels 16 and 17.

Referring back to FIG. 5A, separate clamp plate screws have beenreplaced by one clamp plate screw 40. The clamping surface now becomesthe inside surface of clamp washer 40A which allows for relativemovement (such as by material contraction) of panels 16A and 17A withoutdestroying coupling integrity.

Referring back to FIG. 6, the structure is identical to the embodimentsof FIGS. 4 and 5 with the exception of the angle or bevelled insulativeblocks 41, 42 and 43 to angle front clamp plate 31 with respect to faceportion 14 of hull reinforcer 12 for the purpose of bringing wall panels16 and 17 in a more parallel relationship with a curved section of hull1 1A. Here it is pointed out that the existing or in-place hullstiffeners 12 are normally mounted in this manner with face portion 14in parallel relationship to the centerline of the ship and not to thehull portion at which it is attached.

Referring to FIG. 7, a bulkhead 51 is shown which is accessible fromboth sides allowing insulative blocks 53 and 54 to abut bulkhead 51 oneach side thereof. Here the front clamp plate 57 covers insulative block54 and is held in place via clamp screw 56 passing through clamp plate57, insulative block 54, tubular clamp screw insulator 52, which passesthrough bulkhead 51 and the insulative block 53 on the other side ofbulkhead 51 and its clamp plate 58. In this embodiment, each clamp plateforms a panel nut plate to which panels are mounted via panel mountingscrews in threadable engagement with panel mounting screw holes 59 and61 in clamp plate 57 for example. The same arrangement is on clamp plate58 for hanging panels on the other side of bulkhead 51. Here it ispointed out that there is no metallic heat transfer path betweenbulkhead 51 and panels to be hung therefrom due to the tubular clampscrew insulator 52.

Referring to FIG. 8, a marine panel hanging assembly for utilizationwith a bulkhead accessible from one side only is shown, the bulkheadbeing the section shown as 62. In this embodiment a primary insulativeblock 63 is in abutting contact with bulkhead 62 and is held thereto viaa saddle bolt 68 passing through saddle tab 66 of saddle 67 andinsulative block 63. Bolt 68 is in threadable engagement with a tappedhole in bulkhead 62. A second insulative block is received by saddle 64between upper and lower skirts 71 and 72, respectively, and a thirdinsulative block 74, which is actually a bolt plate, carries a nut plate76 in recess 77 which is then slidably received by saddle 64 with thenut plate 76 in abutting relationship with the second insulative block73. Nut plate 76 has projections to bend over insulative block 73 tocapture the entire assembly. The panel is then hung on bolt plate 74 viapanel screws in panel screw holes 78 and 79 and in threadable engagementwith apertures in nut bolt plate 76 (not shown). Here a heat transferpath is broken by raised face area on plate 74 spatially displacingpanels from a prospective contact area of the wall panel with saddle 64.

Referring to FIG. 9, the operation is exactly the same as FIG. 8 exceptthe saddle tabs 66 and 67 have been eliminated and saddle bolts 68A and69A pass through apertures in the backwall of saddle 64A.

Referring back to FIGS. 10, 11 and 12, it can be seen that metal tometal heat paths between hull 11 and panels l6 and 17 have beeneliminated as in the embodiment of FIGS. 4 and 5.

It should be understood, of course, that the foregoing disclosurerelates to only a preferred embodiment of the present invention, andthat it is intended to cover all changes and modifications of theexample of the invention herein chosen, for the purposes of thedisclosure, which do not constitute departures from the spirit and scopeof the invention.
